摘要：
An ink jet head includes a substrate having an ink supply port, an ejection outlet for ejecting ink supplied through the supply port, and a flow path portion which provides fluid communication between the supply port and the ejection outlet. The flow path portion includes a near portion which is near to the substrate and a remote portion which is remote from the substrate, and a width of the near portion is different from a width of the remote portion in a sectional plane perpendicular to a direction of flow of the ink, and a stepped portion is provided between the near portion and the remote portion.
